Application filed October 6, 1916. Serial No. 124,050.

I My invention relates ,to what I term reserve feed and splicing apparatus and is particularly adapted for use in the manufacture of roofing, or it may be used in the manufacture of other products where it is' necessary to splice the ends of paper, felt fabric, etc., together and where it 'is desirable to have the material fed at a constant and uniform rate to its point of treatment while the splicing operation is being carried on.

In the drawings, Figure 1 is a side elevation of my apparatus; and

Fig. 2 is an end elevation looking from the left af Fig. 1 atthe reserve feed.

In the drawings I have shown my invention in use in the manufacture of prepared roofing in which 1, 1 are rolls of felt mounted on shafts or rollers 2 supported on frame 3 by brackets 4:. I provide any suitable means for keeping a tension on the roll so I as to prevent same from unwinding. 5 is -'a table upon which are supported guide- -rollers 6 and "7 in suitable bearings so arran ed. that the felt 1 passes over the roller 6 and *under'the roller 7. 8 is a frame mounted on .the'table 5 and 9", 9- are dies adapted to be heated and to be brought together so as to compress and heat the spliced oint of the felt between the dies 9, 9. The upper die 9, as shown, is pressed down on the lower die by means of the handle 10 whicli operates. theeccentric 11 to press down the upper die through the link 12. 13,, asshdwn, is a steam pipe lead-' ing to the upper di 14: isa steam pipe leading from the. upper, die to the lower \xdie 9, and suitableoiitletiis provided from the lower die for" the same. The d1es 9 may be heatedsteam' ofheated by gas orelectricallyheated, as d d. 15, 15 are two rollers .mountedin uprights 17, 17, adapted to be moved toward andj away frojn each other in the grooves 18. 191's a haildle or lever adapted to operate eccentric- 20 upon whichv is mounted a link 21 so as press down onthe block 17 and carry with it the .upper' roller 15 to force the two rollers 15, 15 firmly togetherso as to prevent rotation and lock the felt 1 against movement.- The felt 1, having passed through the splicing machine over roller 6, underroller. 7 between the dies 9, 9 and be tween the locking rollers 15,,15, passes to the reserve feed, which I will now describe.

22 is a frame having vertical angle irons 23 arrangedin'pairs so as to provide a vertical slot or track 24:. As shown in the drawings, I have provided four of these vertical tracks or slots, but as many more or less may be used as will obtain" the desired results. 25 are rollers loosely mounted in bearings but fixed in their relation at the bottom of the frame. 27 (see Fig. 2) is a roller. mounted upon a shaft 26, the ends of which shaft are located so as to travel in the track or slot'24. 28 is a sheave fixedly mounted on the shaft 26 around which a flexible support 29 (which may be of rope, chain, leather, or suitable material) passes. .The ends of this support 29, as shown, are fixed at 30 and 31. Of course, if desired an endless belt could be used by the addition of two sheaves locatedabove theframe, but the form shown is the preferred onev .Attached to the top of the frame, or at a suitable location on the frame, are stirrups or brackets 32 supporting sheaves 33 in fixed relation'to the frame.- The flexible support 29"being fixed at 30 passes over the first sheave 33 (from right to left) then sheave 28 mounted on shaft 26, upon which is movable sheave.

34 is an idle sheave, suitably mounted, over which" the flexible support 29 then passes. 35 is a movable bar. 36 is a fixed shaft. Upon the movable shaft are located a series of sheaves 38 supported in brackets or stirrups 37. Upon the shaft 36 are located a series of sheaves 39.. After the 106 flexible support 29 has passed over the sheave 34 it passes 'down around one of the sheaves 38, then over one of the sheaves 39, then 38, then 39, then 38, then 39, then 38 and upto its fixed point 31. The movable 116 bar 35 is movable in a vertical direction and is provided with removable weights 40 adapted to maintain a tension on the support 29. 41 is an endless sprocket, chain passing around sprockets 42, 42 fixedly secured in place on the shafts 43 and 44. This sprocket chain may be moved by means of the wheel 43 provided with a handle 44,

which wheel is fixedly mounted on shaft 45, having a gear adapted to engage with the large sprocket wheel 46 fixedly secured to the shaft, upon which is mounted the lower sprocket wheel 42. The movable bar 35 is fixedly secured to the sprocket chain at saturating tank and through, the reserve feed from the rolls 1.

The operation of my invention is as follows: A roll of felt having been mounted on the supports and passed through the splicing machine and through the reserve feed when it is desiredto splice or attach to it another roll, the locking lever 19 is.

operated to compress the rollers 15, 15 so as to hold the end of the felt 1 in fixed position while the splicing operation is being carried on. As. it is desirable to maintain a constant and uniform passage of the felt throughout the saturation, it will be seen that as the rolls 52, 52 continue to operate, after the locking rollers 15, 15 have prevented any movement of the felt at the end on the splicing table, the felt will tend to pull down on the rolls 27 and the support 29 for these rolls 27 permits the rolls 27 to move down in the track 24 untilthey are in the position shown in dotted lines in Fig. 1. While this takes place the length of the flexible support 29 between the fixed sheaves 33 and the sheaves 28 mounted on the shafts 26 on which the rolls 27 are mounted increases while the distance between the sheaves 38 .and 39 decreases. In other ,words, the movable bar 35 is raised toward the fixed shaft 36 so as to allow the greater art of the flexible support 29 to be used or support-" ing the rolls 27 at tlieir'various positions between the position shown at the top ofv Fig. 1' and the position shown in dotted lines at the bottom of Fig. 1. The weights 40 constantly maintain tension on the support 29 while this is taking place. When the 'splicin operation is completed and the locking rol ers 15, 15 are released the operator operates the wheel 43 rotating the shaft 45, sprocket 46 and lower sprocket 42 so as to move the endless sprocket chain 41. As this is done it carries with it the movable bar 35 fixed to the sprocket chain 41 down until the sheaves 38 and 39 have assumed the position shown in Figs. 1 and 2 in full lines, and the sheaves 28 and the rolls 27 have assumed the position shown in full lines in Fig. 1. As this is being done, of

course, the rolls 52 being constantly rotat ing and constantly drawing the felt, there is no stoppage of the supply of felt passing through the saturating tank and hence a constant and uniform supply is maintained.
